The plate heat exchanger is a static device and is not easy to be damaged. It is only necessary to check whether the three-dimensional temperature, pressure, and flow of the inlet and outlet are within the design range, and whether the plate heat exchanger is leaking. Heat exchangers are widely used. Moreover, it has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, convenient installation and cleaning, wide application, and long service life. So what are the daily maintenance of the heat exchanger?
(1) In general, the heat exchanger can be cleaned without disassembly. The heat exchanger is flushed with water in the direction opposite to the flow of the medium to flush out debris, but the pressure must not be higher than the working pressure, and it can also be cleaned with a non-corrosive chemical cleaning agent for stainless steel.
(2) If the plate is used for a long time, there will be a certain amount of deposit fouling, which will affect the heat transfer effect. Therefore, it must be removed and washed regularly.When disassembling and washing, wash the dirt on the surface of the plate with a brown brush, or use a non-corrosive chemical cleaning agent.Be careful not to scrub with a metal brush to avoid damaging the plates and affecting the corrosion resistance.
